Interference Coordination in Multi-cell MIMO Networks

In this chapter, we present interference coordination techniques for multi-cell networks, where cell-edge users may suffer from severe inter-cell interference. We consider both CSI-sharing cooperation and MIMO cooperation for base stations. In particular, the CSI-sharing cooperation is studied in the context of a downlink scenario where three users are located in the inter-section of three cells, and each user belongs to one cell and receives interference from other cells. A beamforming scheme is proposed to achieve the optimal DoF region of the network. Then, the MIMO cooperation for base stations is also introduced in the form of cloud radio access network (C-RAN), which is an emerging network architecture for the 5G cellular network. The basic principle and implementation challenges of C-RAN are discussed.
